example template for creating new subsystem roles

Role Name

A template for an ansible role which configures some GNU/Linux subsystem or service. A brief description of the role goes here.

Requirements

Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.

Role Variables

A description of all input variables (i.e. variables that are defined in defaults/main.yml) for the role should go here as these form an API of the role.

Variables that are not intended as input, like variables defined in vars/main.yml, variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) can be also mentioned here but keep in mind that as these are probably not part of the role API they may change during the lifetime.

Example of setting the variables:

template_foo: "oof"
template_bar: "baz"

Variables Exported by the Role

This section is optional. Some roles may export variables for playbooks to use later. These are analogous to "return values" in Ansible modules. For example, if a role performs some action that will require a system reboot, but the user wants to defer the reboot, the role might set a variable like template_reboot_needed: true that the playbook can use to reboot at a more convenient time.

Example:

template_reboot_needed - default false - if true, this means a reboot is needed to apply the changes made by the role

Dependencies

A list of other roles hosted on Galaxy should go here, plus any details in regards to parameters that may need to be set for other roles, or variables that are used from other roles.

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: all
  vars:
    template_foo: "foo foo!"
    template_bar: "progress bar"

  roles:
    - linux-system-roles.template

More examples can be provided in the examples/ directory. These can be useful especially for documentation.
